Kim et al. [8] calculated heat transfer coefficients for pasteurization
of orange juice in a plate heat exchanger. The values
for orange juice ranged between 983 and 6500Wm−2 K−1 and
for water between 8387 and 24245Wm−2 K−1. The values
reflected the changes in parameters such as channel velocity,
temperature and heat exchanger section. A correlation
(Nu = 1.12×10−5 Re1.39Pr1.63) was developed to explain the
data, as well as a means for predicting the heat transfer coefficient
from the viscosity and channel velocity.
